To be fair to CloudFlare, Google had a heap issue a few years back (maybe like 7 now) where internal flags and copies of argv (which Google use heavily for config) were clearly present in output from their HTTP frontends, including references to Borg before Borg was ever documented publicly.

Over in App Engine land, someone bypassed their JVM sandbox and managed to extract a copy of their JVM image, which included much of their revered base system statically linked into something like a 500mb binary.

Sorry, I'd have to go digging to find references to either of these incidents. At least in either case customer data wasn't leaking, but suffice to say it's a little bit of the pot calling the kettle black

And finally let's not forget the China incident, which rumour has it, resulted in a system compromise at Google right to the heart of their engineering organization. Of course they didn't get roasted like Yahoo recently did over their password leak
